ATTACHMENT FOR HAT-POUNCING MACHINES.

SPECIFICATION forming part of Letters Patent No. 367,169, dated July 26, 1887.

' Application filed September 8, 1886. Serial No. 212.992.

(No modeLl To all whom it may concern:

Be it known that}, Gnogecn VAN WART, of Yonkers, in the county of Wcstchester and State of New York, have invented a new and Improved Attachment for Hat-Bouncing Machines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a'partof this specification,

- in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of a hat-pouncing machine having my invention applied thereto, and Fig. 2 is an end elevation of the same.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

H The spindle A, which carries the pouncingroller B, is mounted upon the table 0 in the usual manner.

D represents the ordinary support for the hat material for holding the same in contact with the roller B, and upon this support is secured my attachment E, so that the hat material will be worked between the roller B and the edge of the metal plate a of the attachment.

The attachment E consists of the block b, of wood, the said metal plate a, the spring or curved metal arm a, and the guard d, held above the block b and slightly back from the plate a, as shown in Fig. 2, so as not to come in contact with the roller B but effectually prevent the operators fingcrsfrom coming in contact with the roller B.

The plate a is set at a tangent to the roller B, and its upper edge is slightly beveled downward toward the roller, as shown at a, so that the hat material will be worked in an angle formed by the edge of the plate and the periphery of the roller.

' The upper surface of the block bis, by prefupon the attachment E, so that it willbe drawn over the edge of the plate a by the action of the roller B. The operator then places his foot upon the treadle F and lifts the hingedv and curved arm G, to which the support D is attached, upward, which will bring the hat material into contact with the surface of the roller B. The hat material, being worked over the edge of the plate a,will be compressed and faced off upon the lower surface, while its upper surface will be pounced in the ordinary manner by the action of the roller. In this manner both surfaces of the hat material are given a comparatively uniform and similar working, and at the same time, so that much time is saved and the product improved.

- My attachment is applicable to all forms of pouncing-machines that employ a revolving roller.

Having thus described my invention, what I 7 claim as new, and desire to secure by Letters Patent, is

l. The combination, with the pouncingroller B and the block I attached to the arm G, of the bow-spring 0, attached to the block and reaching above the same, and provided with a guard, cl, substantially as described.

2. The combination, with the pouncingroller B, of the hat-supporting block b, provided with the roller f at its upper surface, and provided with the plate a, next to the pouncing-wlieel B, substantially as described.
